School Uniforms and Dress Codes: State Policies PDF - This StateNote lists state policies on school uniforms and dress codes. No states mandate the use of school uniforms. Twenty-three states give local districts the authority to require students to wear uniforms. Indiana, Iowa and New Hampshire authorize local districts to establish dress codes, but do not mention uniforms in the state statute. Massachusetts’ law prohibits dress codes.
